variable d'environnement windows non interprétée

voila

j'ai mon script qui doit écrire un fichier dans %windir%

target[1] = "%WinDir%\\1147405550.exe";

l'echo
cout <<target[1];

%WinDir%\1147405550.exe

std::ofstream file(target[0], std::ios_base::binary);
file << decoded_stub[0];

n'écrit pas le fichier dans windir (ni ailleurs) alors que si je met

target[1] = "%WinDir%\1147405550.exe";

il me l'ecrit dans %cd%\"%WinDir%L7405550.exe

c'est à dire qu'il ecrit un fichier nommé "%WinDir%L7405550.exe
dans le repertoire courant

j'en conclu que %windir% n'est pas interprétée

quelqu'un aurait il une solution ?

Sous windows 2000 et supérieur, il y a ceci:
http://msdn.microsoft.com/library/de...sdirectory.asp

Sinon, il faut que tu le fasses toi-même avec GetEnvironmentVariable(), etc.

Salut !

Bon ben,pourquoi ne pas utiliser l'API GetWindowsDirectory :

Code:

The GetWindowsDirectory function retrieves the path of the Windows directory. The Windows directory contains such files as Windows-based applications, initialization files, and Help files. UINT GetWindowsDirectory( LPTSTR lpBuffer, // address of buffer for Windows directory UINT uSize // size of directory buffer ); Parameters lpBuffer Points to the buffer to receive the null-terminated string containing the path. This path does not end with a backslash unless the Windows directory is the root directory. For example, if the Windows directory is named WINDOWS on drive C, the path of the Windows directory retrieved by this function is C:\WINDOWS. If Windows was installed in the root directory of drive C, the path retrieved is C:\. uSize Specifies the maximum size, in characters, of the buffer specified by the lpBuffer parameter. This value should be set to at least MAX_PATH to allow sufficient room in the buffer for the path. Return Values If the function succeeds, the return value is the length, in characters, of the string copied to the buffer, not including the terminating null character. If the length is greater than the size of the buffer, the return value is the size of the buffer required to hold the path. If the function fails, the return value is zero. To get extended error information, call GetLastError. Remarks The Windows directory is the directory where an application should store initialization and help files. If the user is running a shared version of Windows, the Windows directory is guaranteed to be private for each user. If an application creates other files that it wants to store on a per-user basis, it should place them in the directory specified by the HOMEPATH environment variable. This directory will be different for each user, if so specified by an administrator, via the User Manager administrative tool. HOMEPATH always specifies either the user's home directory, which is guaranteed to be private for each user, or a default directory (for example, C:\USERS\DEFAULT) where the user will have all access.

Dans ce cas, si l'on veut toucher aux dossiers pointés par les variables d'environnement (ex: windir, homedrive, homepath, appdata), on peut carrément s'attaquer à SHGetSpecialFolderPath()...

cool

c'était exactement ça (bravo et merci)

le c++ ça doit etre geant quand on touche bien sa bille

qu'est ce que c'est chiant quand on débute
:D

char szPath[MAX_PATH];

SHGetFolderPath(0, CSIDL_WINDOWS , NULL, 0, szPath ) ) ;

sans oublier

#include <shlobj.h>

je compile avec mingw

merci encore
